Concordium releases Testnet 2

Today we are proud to announce the release of Concordium Testnet 2 which contains new features, bug fixes and documentation improvements.

Testnet 2 is one of our milestones before the release of Concordium Mainnet sometime at the beginning of 2021.

This release is an invite for community members, node runners and users in general to preview the technology behind the curtain and to help us in this testing phase.

What’s in the box?

[Node] — Passive node: A node that participates in the Concordium network. It relays messages, provides an API for submitting transactions and inspecting the chain, and processes blocks, but does not produce any blocks on its own.

[Node] — Baker node: Does everything a passive node does, but in addition participates in consensus, producing blocks.

[Node] — Finalizer node: Does everything a baker node does, but in addition, participates in the finalization part of our consensus.

Upgrade instructions from Testnet 1 to Testnet 2

Last week we announced our software upgrade, if you participated on Testnet 1 but haven’t upgraded yet, please do the following.

• Follow the above steps to download the most recent Concordium software
• Run the reset-data executable from the unzipped archive
• For Mac users: the first time you open the tool, right-click the reset-data file and select Open. A message will appear that the software is from an unidentified developer. Select Open again
• For Windows users: the first time you open the tool, double-click the reset-data file. A message will appear that the software is from an unidentified developer. Select More info → Run anyway
• The tool will ask:
  Do you also want to remove saved keys?
  Accounts that were created for Testnet v1 are no longer valid on Testnet v2. Therefore, if you have stored accounts from Testnet v1 we recommend entering y which will delete all account keys
